The LSU football team dealt with injuries on the offensive line last season, but Thursday's fall practice provided one that the Tigers may not soon forget.
Starting offensive guard Josh Williford suffered a concussion that may have ended the senior's playing career.
The freak injury came in LSU's morning practice session when Williford lay unconscious for about five minutes after a team pileup, according to Jim Kleinpeter of The Times-Picayune.
Williford is no stranger to concussions. He missed the last seven games of last season after being blindsided in a 14-6 loss to Florida.
LSU is known for possessing a power-running game and wearing down teams in the trenches. A lot of that has to do with its physical and dominant offensive line.
When healthy, Williford is one of the better offensive linemen in college football. He has been a consistent starter the past two seasons and is versatile. He is capable of playing at either guard position, and his 6'7", 334-pound frame allows him to bully even the best defenders.
The Tigers return four starting offensive linemen and are expected to have one of the better units in the SEC. While the entire LSU offensive line is talented, Williford was the only senior of the bunch who was expected to start.
Considering the NCAA's ongoing research of concussions and its rules being implemented for player safety, it wouldn't be surprising if Williford misses the entire season.
If this is the end for Williford, backup redshirt sophomore Jonah Austin may be his replacement, judging by the latest LSU depth chart.
The school has yet to comment on the incident.
