Wayne Rooney played no part in the open portion of training on the eve of Manchester United's Europa League clash with Ajax.
Sir Alex Ferguson's squad were put through their paces at Carrington ahead of Thursday's second leg at Old Trafford, when United will be looking to protect a 2-0 lead and set up a last-16 tie against Lokomotiv Moscow or Athletic Bilbao next month.
Rooney was the only significant absentee from the session and could be rested for the European clash with an important Premier League trip to Norwich looming on Sunday.
The remainder of United's first-team squad were present, including midfielder Anderson, who has been missing recently with a knee problem.
Long-time absentee Michael Owen, who suffered a thigh injury in the UEFA Champions League match against Otelul Galati in November, also did some light jogging.
