Former Arizona Wildcats standout Earl Mitchell signed a multiyear contract with the Houston Texans on Wednesday.

Mitchell, the Texans' third-round (81st overall) pick in April's NFL draft, signed a four-year deal worth $3,423,500.

Mitchell's contract is worth nearly $900,000 more than what the Bengals spent on Roy Miller, last year's 81st overall pick.

Mitchell said he wanted to sign the contract early this summer, agent Ron Slavin said, so he can focus on football. The defensive tackle will receive a guaranteed $788,550, even if he is cut.

"Earl's the type of guy who's no-nonsense, a hard worker," Slavin said. "It's like, hey, let's get to work.

"We had a number that we wanted. We got the number we wanted, and we signed."

Mitchell is the fourth Wildcat in three years to sign a multimillion-dollar contract with an NFL team.

Cornerback Antoine Cason signed a five-year, $12 million deal with the San Diego Chargers after they made him their first-round pick in 2008.

Offensive tackle Eben Britton and wide receiver Mike Thomas inked multiyear contracts with the Jacksonville Jaguars a year ago.

Britton, a second-round pick, signed a four-year, $4.6 million deal. Thomas, a fourth-round pick, signed a four-year contract worth $2.72 million.

Arizona's millionaire list should grow by one later this summer when Rob Gronkowski signs with the Patriots. New England traded up to select Gronkowski, the Wildcats' record-setting tight end, with their second-round (42nd overall) pick in April's draft.

Gronkowski should receive more than the $4.2 million the Bills gave safety Jairus Byrd, last year 42nd overall pick.

Wednesday's signing capped a whirlwind few months for Mitchell. The 6-foot-2-inch, 295-pounder said he was shocked when the Texans, his hometown team, made him their third-round pick. Mitchell grew up in Texas, attending North Shore High School.

Mitchell has impressed Texans coaches in off-season drills, Slavin said.

"Earl's been getting some reps with the 1s already," he said.
