Houston star guard Marcus Sasser pronounced himself as 90 percent recovered from his groin injury on Thursday, one day before the top-seeded Cougars face fifth-seeded Miami in the Sweet 16 at Kansas City, Mo.Point guard Jamal Shead (knee) also confirmed he is ready to play in the Midwest Region semifinal.Sasser has been dealing with the injury since being hurt during a victory over Cincinnati in the American Athletic Conference tournament semifinals on March 11. He missed the AAC title game loss to Memphis and reinjured the groin during a first-round NCAA Tournament triumph over Northern Kentucky.Last Saturday, Sasser played well against Auburn and had 22 points and five 3-pointers in the Cougars’ 81-64 victory. The groin has continued to improve this week.”I’ve just been doing a good job getting treatment, massages, stretches,” said Sasser, who averages a team-best 16.9 points per game. “I’d say I’ll probably be around 90 percent by Friday, so I’ve been getting healthy.”Shead hurt his knee against Northern Kentucky and had 10 points and five assists in the victory over Auburn. But he was just 2-of-8 shooting and missed all four of his 3-point attempts.”Mine was just a bang-up (play),” Shead said. “So I’m back to 100 percent in just these couple of days to recover. I’m back to being pretty good.”Shead averages 10.4 points and a team-best 5.4 assists.Houston (33-3) is two wins away from getting to play in the Final Four in its hometown. But Cougars coach Kelvin Sampson refuses to look past the next 40 minutes.
