ENGLEWOOD—Rookie receiver Carlos Henderson could miss some time after he suffered a thumb injury early in the Broncos’ preseason game Thursday night against the Chicago Bears.

Henderson tried to play through the injury without notifying the training staff, but it was obvious through the two kickoffs he dropped that the thumb was affecting his play.

He did not practice Saturday as he was undergoing tests to determine the severity of his thumb injury.

Henderson was the first of the Broncos’ two, third-round draft picks this year, No. 82 overall. He had 82 catches for 1,532 yards and 19 touchdowns as a junior at Louisiana Tech last year and added two more rushing touchdowns and two more scores off kickoff returns.

He has so far struggled with the transition to the NFL as most rookie receivers do.
