He considers it a bonus when he can practice for a full week. McNair dislocated a finger early last season and was playing with a strained calf muscle and a cracked bone spur in his ankle at the end of '03.
He started 111 straight games for the Titans despite an endless string of injuries, and in last season's wild-card win over the Ravens, he dislocated his shoulder but still had 88 yards on 25 carries.
All fullbacks are tough, but in a game against the Bears in 2002 he played with a cracked bone in his back. He took on Brian Urlacher, and his blocking set up James Stewart for a 172-yard rushing day.
