Northampton Saints play down George North injury fears
Northampton director of rugby Jim Mallinder has played down fears over Wales wing George North's calf injury.
North, 22, limped off the field after 20 minutes of Northampton's Amlin Cup semi-final win over Harlequins.
"George North has a calf strain, hopefully it's not too bad," Mallinder said
"He picked it up in the warm-up and thought he was okay to carry on but clearly wasn't 100%."
