Doncaster hit by injury jinx

Doncaster manager Brian O'Driscoll was left to rue his side's injury jinx after Ryan Mason became the latest member of his squad to suffer a serious blow.The midfielder, who is on loan from Tottenham, is facing several weeks out having been carried off with ankle ligament damage following a heavy challenge from Tranmere's John Welsh late in the Yorkshire side's 3-0 Carling Cup first-round victory.It came just three days after Rovers saw strikers Billy Sharp (ankle) and James Hayter (knee) both leave the Amex Stadium pitch on a stretcher in the club's 2-1 season-opening defeat at Brighton.Already out injured are James O'Connor, James Chambers, Martin Woods, Brian Stock, Adam Lockwood, Shelton Martis and Mark Wilson.O'Driscoll told BBC Radio Sheffield the extent of Mason's injury, saying: "He's damaged his ankle ligaments, it's non-weight-bearing so he's another one to leave the ground on crutches."We'll have to assess him in a couple of days, he's a Tottenham player so he'll have to go back for them to have a look at him but it's going to be weeks I think rather than days. Someone said we've run over a cat, I think we've run over a litter of black cats."
