John McClain of the Houston Chronicle and Sporting News is reporting that Houston Texans All-Pro receiver Andre Johnson will undergo another MRI on Monday to evaluate his injured right hamstring. Johnson left left Sunday's 17-10 win over the Pittsburgh Steelers in the second quarter after catching a 10-yard pass and going down untouched.
Texans head coach Gary Kubiak said after Sunday's game that the team wouldn't speculate as to Johnson's availability for this Sunday's game versus Oakland until further tests were conducted. Houston lost Johnson and backup running back Ben Tate (groin) on the same day that their other playmaker, running back Arian Foster, returned from a left hamstring injury suffered in the preseason. According to McClain, Tate's availability won't be known until later this week.
Johnson has 352 yards and two touchdowns on 25 catches through four games this season, second in the AFC in receiving behind New England's Wes Welker.
