Scan results on Jalal's calf problem showed a slight muscle strain of the Soleus (the muscle below the calf).
While Howe is hopeful Jalal will recover in time, the injury means the Cherries number one is doubtful for Saturday's clash at Morecambe, with 18-year-old Dan Thomas again on standby.
But Howe also hasn't dismissed the prospect of an emergency seven-day loan if Cherries require one and providing the Football League grant the club permission to recruit a stopper.
Discussing the situation yesterday, Howe told the Echo: We're still hopeful Jal will be fit, but we won't know until late on.
Dan has a nagging back problem which he has had for two to three weeks. He isn't 100 per cent fit and hasn't been for the games he's played.
That leaves us without a 100 per cent fit goalkeeper and we'll wait and see if the league let us have an emergency goalkeeper, if come tomorrow we need one.
Should Howe need to bring another keeper in and the league relaxed Cherries' transfer embargo to allow him an emergency loan deal, one likely signing could be Marek Stech.
Howe ran the rule over the West Ham keeper in training last week as a precaution, with Jalal struggling to overcome the ankle problem which kept him out of the FA Cup defeat against Notts County. But the Cherries star recovered in time to face Barnet before suffering the calf injury against Shrewsbury on Saturday.
