Manchester United will gave late fitness tests to Carlos Tevez and Jonny Evans ahead of Saturday's Premier League trip to Bolton Wanderers.
Sir Alex Ferguson has confirmed that both striker Tevez and central defender Evans are in contention for the Reebok Stadium clash despite picking up knocks in Wednesday's 1-0 victory over Wigan Athletic.
Ferguson is keeping his fingers crossed that Northern Ireland international Evans is given the green light as his defence is already weakened by the absences of Rio Ferdinand (back) and Patrice Evra (foot).
United's defensive options are stretched to such an extent that reserves captain James Chester has been placed on standby to join the first-team squad.
"We limped over the line on Wednesday night when we picked up quite a few injuries. At this time I couldn't tell you what my side is going to be," admitted Ferguson.
"We've got fitness tests on two players, possibly three, on Saturday morning.
"Tevez and Evans are major doubts. They will have a fitness test at 10am. There are one or two others that are doubtful.
"I've brought James Chester into the squad. Although he hasn't played in the first team, he is still a capable young player. If it has to be, then it has to be. That's why we have a big squad.
"But with Wes, Rio and Patrice all out, it would be a major blow if Evans isn't available, particularly because of the form he has been in."
Striker Wayne Rooney will also miss the short trip to Bolton with the hamstring injury picked up against the Latics.
