'Brian Campbell's chances of earning a spot on the Buffalo Sabres' defense were enhanced yesterday when highly touted rookie Henrik Tallinder suffered a knee injury. Tallinder's left knee was badly sprained as it twisted awkwardly following a legal check by defenseman Dmitri Kalinin. The hit, which will keep Tallinder out indefinitely, was during a training camp scrimmage at Jack Gatecliff Arena. Campbell and Tallinder were expected to compete for what quite likely is one opening on defense.'
