Cleveland Browns rookie quarterback Colt McCoy is not practicing because of a minor thumb injury sustained in his NFL exhibition debut.

McCoy hit his hand on the helmet of one of his teammates on a throw in the third quarter of the Browns' 27-24 win at Green Bay. Browns coach Eric Mangini said Monday that McCoy is "fine" and will only miss a day or two. Mangini expects McCoy, a third-round pick, to play in Saturday's home game against St. Louis.

McCoy finished 5 of 10 for 25 yards and two interceptions before leaving with the injury. The former Texas star is expected to be Cleveland's third-string quarterback this season, spending the year learning behind Jake Delhomme and Seneca Wallace.
