IRVING, Texas — The Dallas Cowboys placed defensive tackle Jack Crawford on season-ending injured reserve Wednesday because of a broken thumb and activated linebacker Keith Smith from the practice squad.
Safety Jeff Heath also broke a thumb in last weekend's win at the New York Giants and is listed as doubtful for Thursday's game against Philadelphia.
Receiver Terrance Williams was listed as probable despite breaking an index finger against the Giants. He's expected to play with a splint.
Smith has played in four games while bouncing around from the roster to the practice squad and the waiver wire.
