The speedster didn't get the medical results he was looking for as he was unable to practice for the next two days.
Thompson tried it again this week and was able to practice for the past few days on a limited basis without incident.
"I kind of had a little reaction to it last week, it was more precautionary to see how it holds up," Thompson said. "You don't know until you try. It's healthy now. I'm in the process of getting that little bit of soreness out."
Signed last year as an undrafted rookie out of Florida, Thompson ran the 40-yard dash in 4.28 seconds at his campus Pro Day workout.
The Ravens are hoping to eventually inject that speed into their offense and return game. Thompson averaged 25.9 yards per kickoff return as a rookie and caught five passes for 51 yards.
"He’s practicing as a kick returner, he’s practicing in the other phases as well," special teams coordinator Jerry Rosburg said. "The decision will be made on Sunday as to exactly who we have up and what roles they’re going to have. Deonte demonstrated a year ago that he has the skills to do that.
"So, he’s had success, too, and he understands it. I think he’d probably be pretty excited about that opportunity should it come his way.”
