FAYETTEVILLE, Ark. — The MRI conducted on injured Arkansas guard Brandon Dean’s right knee came back negative, but the second-leading scorer for the Razorbacks could miss up to a month, according to team physician Dr. John Park. Dean, who averages 14.3 points a game and ranks fourth in the Southeastern Conference with a .543 field goal percentage, injured his knee while being fouled on a layup attempt in the final two minutes of Saturday’s 70-64 loss to Ole Miss. Dean had 11 points on four of nine shooting before leaving the game. The MRI showed no ligament or cartilage damage, but the Monroe, La., native does have a knee sprain and a bruised bone. According to team trainer Dave England, Dean iced the knee on Sunday and will begin motion treatment on Monday. There is no prediction on when Dean, the MVP of the 2000 SEC Tournament, will get back on the floor. Dean has made 50 percent of his shots, or better, in 12 of 17 games, has led the team in scoring seven times and has had four 20-point games with a career-high 29 points against then-No. 5 Illinois. The Razorbacks (10-7, 2-3) return to practice Monday afternoon to begin preparations for Wednesday’s 6:30 p.m. game at No. 20 Georgia, which is not televised.
