Dyson has been on the 15-day disabled list since mid-May due to a high ankle sprain. He has hit .268/.286/.561 with one home run and six stolen bases in 41 at-bats for the Royals this season.

Dyson said he thinks he's getting closer to going on an injury rehab assignment, though nothing is planned. 

Dyson was hitting .268 in 41 at-bats before the injury with a homer, eight RBI and six stolen bases. 

"I still feel a little pain there," he said, "but it’s just a process I’ve got to go through. I went 90 feet four times. They were just trying to get a gauge if the pain stayed with me after I stopped. It’s going away when I stop."

Dyson does not have a timetable to return for the Royals. 

"I don’t know anything yet," he said. "Maybe after (the club) comes back off the road (following a weekend series at Texas), I’ll know a lot more. I feel I’m going to be all right. I’ve made some pretty good progress and, hopefully, I’m back in the lineup within a couple of weeks."

Dyson is already doing hitting and throwing drills -- while wearing a boot -- but has not yet begun running. He hopes to do so Tuesday, according to MLB.com.

"With a high ankle sprain, you can't really rush it," Dyson said. "You've got to make sure you are able to go out there and help the team. I'm not going to say I want to be 100 percent, but if I'm close, then I am ready to roll."

The Royals have lost seven of eight games since Dyson injured himself May 15, and he is not expected to return to the field for another two or three weeks.
