Motherwell goalkeeper Darren Randolph has had his two-game ban upheld by the Scottish Foofball Association's judicial panel.
SFA compliance officer Vincent Lunny had issued a complaint after Randolph appeared to kick out at Hearts' Callum Paterson.
Motherwell appealed the suspension, but they have failed to have the ban overturned with the judicial panel feeling the incident constituted violent conduct.
It means Randolph will miss this weekend's Scottish Cup game against Aberdeen as well as the SPL encounter with Ross County.
Lee Hollis is set to replace Randolph in Stuart McCall's side for those two games.
The 32-year-old, who holds the Cumbrians' record for most appearances for an outfield player, has missed the last two matches and will be sidelined for another four to six weeks.
Danny Livesey and Mike Edwards have formed a partnership in central defence in Murphy's absence and are expected to continue in the FA Cup clash with Bournemouth on Saturday.
On-loan teenage pair Valentin Gjokaj (derby) and Sean McGinty (Manchester United) are also pushing for a place in manager Greg Abbott's starting line-up.
Yussuf celebrated his return to action with a goal after coming on as a substitute in Tuesday's reserve match against Tranmere. But five minutes later, the 20-year-old suffered a recurrence of the groin injury that has kept him out of the first-team squad since mid-October.
Albion are waiting to discover the extent of the problem but the former Leicester trainee is set for an extended spell on the sidelines.
Some good news for manager Gary Rowett saw Aaron Webster play the full 90 minutes in the 2-2 draw in his first run-out since suffering a hamstring injury in training more than a month ago.
Rowett also gave loan signing Jacob Blyth his first full outing. The young Leicester striker had previously made brief appearances from the bench in the League Two defeats against Aldershot and Wycombe.
