Texans coach Bill O'Brien halted practice early Wednesday, a decision made following a session where wide receiver Jaelen Strong limped off the field.
Strong wasn't injured seriously, though.
"I think he's all right," O'Brien said.
The practice continued after Strong limped off, but it was eventually cut short by O'Brien.
Following the organized team activity, O'Brien took issue with the NFL offseason rules regarding practices mandated under the collective bargaining agreement.
Physical contact isn't permitted during offseason practices, but it's difficult for players to not knock into each other while still going full-speed and avoid injuries.
