"I'd like to be back out there tomorrow," Wells said. "I'm hoping though, within the next two to three weeks, to be back on the field. They are telling me closer to three weeks."
After injuring his right groin May 9 against the White Sox and placed on the 15-day disabled list the next day, Wells said he could tell something wasn't right by the way the groin sounded as he hurt it.
"Any time you sort of hear something pop, it isn't a good thing," Wells said. "The hard thing for me is trying not to come back too soon. It is a struggle.
"I need people around me to tell me to slow down, and that is what they are doing."
Wells took part in movement drills in water on Saturday and continues to do strengthening drills around his core, but he still is not running.
While the pain has subsided and he has had no setbacks, Wells said the rehab has worn him out.
"They are happy with the progression," Wells said. "They put you through so many different things. It is a matter of strengthening everything around it and then getting to movement and swinging, which should be the last thing.
"I'm not allowed to swing the bat or do too much. I don't want to have a setback."
Struggling at the plate in 35 games before being placed on the DL, Wells hit .183 with four home runs and 13 RBI.
