Everton manager David Moyes is facing up to being without some key players at home and abroad.
Defender Sylvain Distin will miss the second leg of the Europa League last-32 tie against Sporting Lisbon a week tomorrow in Portugal after being sent off last night. Distin was red-carded after bringing down Liedson in the area with only four minutes remaining and Miguel Veloso converted the penalty.
It could yet prove to be a vital away goal after Steven Pienaar and Distin had found the target.
Moyes was left frustrated despite the victory, and injuries did not help his mood. Marouane Fellaini sat out the 2-1 win and is expected to miss the rest of the season as he needs ankle surgery.
Tim Cahill then came off with a calf problem and is likely to be assessed today, with Manchester United next up on Saturday.
Fellaini will again be looking on from the sidelines after being injured in a challenge with Liverpool's Sotirios Kyrgiakos, who was sent off, in the derby a couple of weeks ago.
Moyes said: "Fellaini is not good. He has an injury similar to (Arsenal striker) Robin van Persie and that could keep him out for six months. We will not be sure until the operation takes place.
"He has played really well this season and been part of the reason behind our improvement. He's a big miss to us already."
Moyes could not hide his disappointment at the way Everton let Sporting back into the tie.
Pienaar made the breakthrough in the 35th minute with a good finish after being set up by Cahill.
Distin extended Everton's lead in the 49th minute after goalkeeper Rui Patricio flapped at Leighton Baines' corner.
