Newcastle boss Rob Andrew believes injured centre Jamie Noon can recover in time to take the field for England in Cardiff next Saturday.
Noon was set to make his first RBS 6 Nations start against Wales before being forced off after a first-half collision in the 32-13 defeat at Saracens.
The 25-year-old looked devastated as he limped off after taking a heavy blow on his left thigh and receiving attention from the Falcons medical staff.
But Andrew insisted Noon's dead leg could respond to treatment over the next 48 hours and ease England boss Andy Robinson's injury problems.
''He's got a dead leg and we won't know how bad it is for another 48 hours,'' said Andrew.
''If dealt with properly, you're normally okay. We got him off pretty much straight away and that's one of the important things. I think he'll be fine.''
If Noon does not make it, Robinson may turn to Bath's Olly Barkley to fill the position following injuries to Mike Tindall, Will Greenwood and Stuart Abbott.
The injury overshadowed a stirring Saracens performance as they outgunned the visitors up front with all four tries coming from forwards.
Teenage centre partner Mathew Tait is expected to win his first cap against Wales and despite being starved of ball he looked the part in defence and attack, putting Ollie Phillips in for Newcastle's consolation score.
Tait's pass for the try was world class, said Andrew.
He's ready to play for England next week.
