Double doubt for Doncaster

Shelton Martis and Giles Barnes are injury doubts for Doncaster as Dean Saunders' relegated outfit prepare to travel to npower Championship strugglers Coventry.

Defender Martis has endured an injury-plagued campaign and he was substituted with a calf injury during the midweek draw at Middlesbrough, while midfielder Barnes - an unused substitute at the Riverside Stadium - has a back problem.
Winger Kyle Bennett did come off the bench on Tuesday night and suffered no adverse reaction to his recurring toe injury, while youth teamer James Husband will be hoping for further action having made his senior debut as a second-half replacement for Martis in the north east.
Habib Beye is once again absent from the Rovers defence as he completes a two-match ban for his red card in last weekend's 4-3 defeat to Portsmouth.
Brian Stock (groin) and Tommy Spurr (broken hand) are out for the rest of the season, while El-Hadji Diouf (hamstring) is also unlikely to feature again this term.
Midfielder Martin Woods (knee) and forward Habib Bamogo (hamstring) have returned to training, but the Ricoh Arena clash comes too soon for them.
