Bowyer is booked for late challenge during the last Chelsea attack.
That should have been a goal. Kalou again does well down the right and his chipped cross is met by Malouda 8 yards out but he completely slices the ball and it goes wide.

Were underway again at St Andrews.

Birmingham are back in this game now as Ridgewell has a header just over the bar.
Chaos in the Chelsea box! Didier Drogba lies injured on the turf as Liam Ridgwell's shot is deflected in by Benitez. The linesman's flag denies him again, though replays show the injured Drogba playing Benitez onside!
Joe Hart does it again! Lampard fires in a volley only for Hart to tip over from point blank range, brillant stop from the England 'keeper, Lampard can't believe it.
Close call! Benitez finds himself clean through only for the offside flag to deny him - replays though suggest he might have been onside.
What a save! Florent Malouda and Ashley Cole combine to set up Daniel Sturridge, whose goal bound shot is tipped wide by Joe Hart. It looked in all the way.

Birmingham City welcome table-toppers Chelsea to St Andrew's on Boxing Day with both outfits eager to get back to winning ways.
Following a poor start to this season's Premier League campaign, Birmingham have startled many as they remain on a lengthy unbeaten run.
They have won six and drawn three of their last nine games and Carlo Ancelotti's Chelsea should offer a stiff test if they are to take that spell to ten matches.
Alex McLeish watched his City side pick up a 1-1 draw at Goodison Park on Sunday afternoon as their resolve continued to shine in unfavourable situations.
Seb Larsson equalised Diniyar Bilyaletdinov's opener as the second city outfit continue to rise up the table. They now sit in seventh place, one place ahead of Liverpool.
Chelsea only managed a 1-1 stalemate at West Ham United and they have looked a mere shadow of the side that had won five Premier League games on the spin without conceding through October and November.
They have now won just one of their last six fixtures in all competition and this record will be infuriating Ancelotti.
He will know a win at St Andrew's won't come easily with Birmingham in such fine form.
Frank Lampard has notched in the last two games and he seems to have put his shooting boots back on again.
Cameron Jerome has started to find the net for City after a slow start to the season and he will want to aid his burgeoning reputation with another explosive display against John Terry and Ricardo Carvalho at the heart of the visitors' backline.
Chelsea's Didier Drogba will play his last game before leaving to play for Ivory Coast at the African Cup of Nations in Angola.
Nicolas Anelka has been in exceptional form on all fronts this term, but he is missing with a calf strain.
Ancelotti may put his faith in the youth with Daniel Sturridge and Fabio Borini in line for a starting berth and they will want to help extend their four point lead at the top of the Premier League table.
The title challengers will still be without Michael Essien (hamstring) and Jose Bosingwa (knee).
Table-toppers Chelsea produced another classy performance but the only ingredient missing was a winning goal as battling Birmingham bravely maintained their impressive unbeaten run.
It was not a particularly happy game for Chelsea as, in the 89th minute, Florent Malouda was sent off for a second yellow card.
Dogged determination by Birmingham enabled them to collect another valuable point to maintain their creditable league position.
Once again Birmingham competed well against a top-four club and, on this occasion, they were often indebted to a superb display from their on-loan goalkeeper, Joe Hart.
Birmingham may still be looking for their first win over Chelsea in 29 years but they can be delighted with the point from a hectic goalless draw.
The match was a dream come true for avid Chelsea fan, Roger Johnson. The Birmingham defender came up against his hero, Didier Drogba, and emerged with a great deal of credit as he prevented the best striker in the world from scoring.
Chelsea, unbeaten in their previous 15 games against City, had numerous chances but, on this occasion, weak finishing and the goalkeeping skill of Hart prevented them from winning.
In the circumstances Chelsea boss, Carlo Ancelotti, who does not believe he needs to add to his squad in the transfer window next month, was often a placid, emotionless figure on the touchline as his side struggled to take control.
The story could have been entirely different if Cameron Jerome had scored in the opening minute following a solo run. This miss only appeared to spur Chelsea into a ten-minute spell of attacking pressure as they laid siege on Birmingham's goal.
Birmingham weathered this storm but Chelsea's star team were well in control with Drogba showing his potential danger. He produced one powerful shot on the volley which flew just wide as he began to find his range.
Shortly afterwards Birmingham were indebted to their young England goalkeeper, Hart, who dived low to his left to palm away a Danny Sturridge effort.
There was a controversial moment in the 27th minute when Frank Lampard ran through into an offside position. He gathered the ball and, with only Hart to beat, lofted his shot over the bar as if he was playing at Twickenham.
Birmingham were seemingly out of luck with linesmen's decisions as Christian Benitez tapped home from only a yard out from Liam Ridgewell's pass only to be ruled offside, while Sturridge fired just wide just before the break.
There was an anxious moment for Chelsea on the hour. Malouda was booked for a foul on Benitez and, after saving Seb Larsson's free-kick, Petr Cech smashed himself against a post and had to receive treatment.
With the encouragement of the Birmingham fans, Hart continued to thwart the Chelsea attack. Substitute Salomon Kalou had a wonderful opportunity but he jinked the wrong way and Hart was able to block his eventual shot.
In an attempt to break the stalemate Ancelotti took off Lampard and sent on Joe Cole to give the midfield a different dimension.
It was all to no avail although Drogba very nearly took advantage of a bad back-pass from Birmingham skipper, Stephen Carr. His late challenge caught Hart who had to receive extensive treatment for a head injury.
Malouda then received his marching orders for a foul on Carr to sum up Chelsea's afternoon.
