**Mike Catt's injury-ravaged season has taken another downward turn - effectively ending his England hopes until the Six Nations Championship kicks off in February.
Fly-half Catt lasted barely 16 minutes of Bath's impressive 24-20 Zurich Premiership victory against Newcastle before limping off due to a recurring hamstring problem.
The 56 times-capped international was once again forced to retire, and detailed medical analysis will now be required as he faces a potential further spell on the sidelines.
Had he played a full game at Kingston Park, then it is understood that England would seriously have considered him for next Saturday's Twickenham appointment with South Africa.
**Ireland coach Eddie O'Sullivan has named his squad to face Argentina on Saturday at Lansdowne Road, welcoming back a host of stars as Girvan Dempsey, Keith Gleeson, Victor Costello and Gary Longwell all return.
** Wales boss Steve Hansen has promised Swansea's Colin Charvis the Welsh captaincy for the longer term - as long as his form is good enough.
The back-row forward led Wales to their third successive victory with the 32-21 defeat of Canada in Cardiff on Saturday.
Charvis took over the Captains responsibilities from Scott Quinnell for Wales Test series against South Africa of last summer.
Charvis is the natural successor to the 'Mighty Quinn' - following Quinnell's decision to retire from international rugby. SQ won his 52nd cap on Saturday when he came on as a second-half replacement for Dafydd Jones.
**France coach Bernard Laporte has opted to stick with the same 24-man squad that drew with New Zealand (20-20) and beat South Africa (30-10), for Saturday's clash with Canada at the Stade de France.
**Edinburgh Gunners centre Simon Webster has been handed his Scotland A debut for the game against Fiji at Stirling on Wednesday.
Webster steps up to take the place of Rory Kerr, while Gavin Kerr moves into the side in place of Craig Smith.
