Minnesota Vikings linebacker Erin Henderson suffered a concussion during the team's Week 2 loss to the Indianapolis Colts and did not play in Week 3, but he hopes to get back on the field against the Detroit Lions.
Vikings head coach Leslie Frazier told the media on Thursday that Henderson has yet to pass all required concussion tests, but noted that the linebacker could still play if he is able to practice on Friday. Henderson sat out of practice on Wednesday and Thursday.
The 26-year-old defender has been credited with 22 tackles so far this season to go along with two sacks, so it would be a boost to the defense if he could return on Sunday. Henderson played in 15 games for the Vikings last season, recording 70 tackles and 1.5 sacks during that time. Marvin Mitchell -- who has been filling in for Henderson but is nursing an ankle injury -- had full participation in practice on Wednesday and Thursday.
The Vikings and Lions are set to clash at 12 p.m. CT on Sunday, Sept. 30.
