The Sooners could be without Jarvis Jones for the first half of next season after the starting right tackle tore a tendon in his right patella during Friday’s practice. Jones had surgery Saturday. “We were in a team period and it just buckled on him,” coach Bob Stoops said. Jones is expected to be out six months, meaning the Sooners might not get him back until October. Jones, who has 10 career starts, was projected to replace Eric Mensik and be OU’s full-time starting right bookend after splitting time with Donald Stephenson at left tackle last season. With Jones out, the Sooners will likely turn to freshman Daryl Williams and sophomore Josh Aladenoye to fill the void. Williams redshirted last season, while Aladenoye appeared in 12 games as a reserve.
