BOSTON - CELTICS star forward Kevin Garnett could miss the entire NBA play-offs after failing to recover fully from a long-standing knee injury, the defending champions coach Doc Rivers said on Thursday.

MANCHESTER - MANCHESTER United forward Wayne Rooney has warned Everton he will put sentiment to one side in Sunday's FA Cup semi-final against his former club.

LONDON - ARSENAL suffered another injury blow ahead of Saturday's FA Cup semi-final against Chelsea after Arsene Wenger revealed teenage left-back Kieran Gibbs has a groin problem.

Gibbs deputised for Gael Clichy in Wednesday's Champions League quarter-final second leg win over Villarreal, but the 19-year-old finished the tie limping and is a doubt for the Cup semi-final.
