Burchnall said "He trained and he felt okay to do that.
"We kept him away from any contact but we checked him after the session and he seemed alright.
"It was just a bit of a big hit at the time and I think sometimes you've got to have a bit of caution with those things.
"He came off as a matter of precaution but hasn't shown any other signs that he's got concussion, so hopefully he's okay."
