Chris Walker out for a month

South Sydney centre Chris Walker will be out for a month after fracturing a bone in his arm during yesterday's heart-breaking National Rugby League loss to Brisbane.

Walker damaged the radius bone in his left forearm attempting to make a try-saving tackle on Brisbane utility Casey McGuire in the 51st minute of yesterday's thriller at Aussie Stadium, won 22-20 by the Broncos.

He's expected to back in mid-April. Kiwi forward Fili Lolohea needed 26 stitches after suffering a head cut while five-eighth Ashley Harrison required 12 stitches to a gash on his forehead.
