Hurling:Dublin's Padraig O'Driscoll has been ruled out of Saturday's All-Ireland SHC qualifier with Tipperary in Parnell Park.
The Lucan Sarsfields full forward suffered a dislocated elbow late in last Saturday's defeat to Cork.
The injury occured as a result of colliding with Diarmuid O'Sullivan.
O'Driscoll is set to have a check-up later in the week to determine if he can play any further part in the season.
Meanwhile, Tipperary manager Babs Keating has said he's considering fielding a weakened team for the weekend's clash with Dublin.
Following last Saturday's four point win over Offaly, Tipp are almost certain to make the All-Ireland quarter-finals if they win in Parnell Park.
The game will be the fifth consecutive match for the senior side, but the under-21 team have a crucial Munster championship match against Cork on Tuesday, and Keating may rest under-21 players allowing them to be fresh for the game.
"There's a vein of good will running through all selectors in this county and the cooperation between Fr Tom Fogarty as under-21 manager and ourselves is great," said Keating.
