Yu Darvish is scheduled to start on Sunday against the Tampa Bay Rays.

It will be the right-hander's 2014 debut, which has been delayed because of a stiff neck. He is currently on the disabled list.

The Texas Rangers have determined that his bullpen sessions have been good enough that he won't require a rehab start.

Darvish threw an 86-pitch bullpen session on Tuesday that was close to a simulated four innings, where he got up and sat down.

He hasn't faced a hitter swinging a bat since March 16 in Arizona.
