Schaub suffered the bloody injury Sunday when Broncos linebacker Joe Mays sacked him after the ball was thrown in the third quarter of the Texans' 31-25 win over the Denver Broncos, the Houston Chronicle reported.
Mays was penalized for a late hit, but the Texans' team doctor didn't see any signs that Schaub suffered a concussion. The quarterback left the game to deal with the bleeding ear, but came back after one play.
Texans Coach Gary Kubiak was impressed. "Boy, he played like a champ today," he said of Schaub, who ended the game with 290 yards passing, 17 of 30 passes completed, four touchdowns, one interception and a 115.3 passer rating.
"I felt fine," Schaub said after the game. "You know, I just lost a little piece of my ear."
