Northampton Saints utility back Mark Tucker may miss the rest of the season with a broken hand.
Tucker, who played on the wing against Saracens on Saturday, fractured his left hand and was replaced by Johnny Howard in the 64th minute.
It means the 23-year-old former England U21s captain will miss the final four matches of Saints' league campaign, starting with London Wasps at the Causeway Stadium on Sunday.
Tucker has scored three tries for Saints this season.
