Lamar plays Sam Houston State in Beaumont on Oct. 27.
Sims, who was rated the No. 2 all-purpose back in the nation coming out of high school, was considered one of the gems of OSU's 2011 recruiting class. He was the Cowboys' No. 3 running back as a true freshman last season, finishing with 31 carries for 242 yards and two touchdowns.
COWBOYS LEAD NICKLAUS INVITE
The Oklahoma State men's golf team finished first-round play Monday with the lead at the Jack Nicklaus Invitational in Dublin, Ohio. The Cowboys finished with a 295 team score, which was seven shots better than Kentucky and Brigham Young. OSU junior Ian Davis shot a 1-under-par 71 and stood one stroke behind leader Greg Eason of Central Florida.
The final round at Muirfield Village Golf Club is scheduled for Tuesday.
