EAST LANSING, Mich. — Michigan State point guard Kalin Lucas had surgery Tuesday to repair his ruptured Achilles tendon, coach Tom Izzo announced at his afternoon news conference.

Izzo said Lucas would go to Indianapolis to watch his teammates play Butler on Saturday in the Final Four, but he's not sure if he'll be healed enough to travel with the team by bus on Wednesday.

"When I talked to his mom and dad, his mood was great because he was still sleeping," Izzo said jokingly. "He's going to be OK; it's just going to take some time."

Junior guard Durrell Summers accompanied Lucas to the hospital.

"I was at the surgery the whole time," Summers said. "Everything went well."

Junior guard Chris Allen, who has a torn ligament in his right arch, is "moderately improving," but his practice time will be limited, Izzo said. Sophomore forward Delvon Roe's practice time will be more limited because he's playing on a torn meniscus in his right knee — he'll undergo surgery when the season ends.

Allen said his practice Tuesday consisted of only shooting.

"I've got two games under my belt with this injury now, so hopefully, this one will be better because I'll be a lot more rested and my foot will be a lot more healed," Allen said about playing Saturday. "Time will tell."

Roe said he only shot free throws and that his knee remained sore. He knows he'll play only two more games at the most before surgery.

"It is comforting knowing that you're playing in the final weekend of the season," Roe said. "The reason why you didn't have surgery is for this moment."
