Wales trio Leigh Halfpenny, Alex Cuthbert and Mike Phillips were forced to miss training on Tuesday with minor knocks.
The team is currently preparing to take on Ireland in their penultimate Rugby World Cup warm-up match on August 29.
All three are expected to recover in time for the trip to Dublin at the end of the month.
"We had a tough session this morning and they are just feeling the effects of a couple of bumps," forwards coach Robin McBryde is quoted as saying by Sky Sports News. "We didn't feel it was worth risking them this afternoon."
Wales were beaten 35-21 by Ireland in Cardiff on Saturday.
