The Estonian will miss the visit of Ross County on Sunday after being sent off in the 4-3 defeat against Inverness last weekend.
Otherwise, manager Stuart McCall has the luxury of a full squad to choose from, including SPFA player of the year Michael Higdon, who is in the squad despite his brush with the authorities earlier this week.
County have lost midfielder Rocco Quinn to a broken nose while Stuart Kettlewell and Mark Fotheringham have been added to Derek Adams' squad.
Earlier in the week Sam Morrow left the club and County are understood to be running the rule over a number of new recruits, including Moldovan international defender Petru Racu, who was recently on trail at Ipswich Town.
County's slim hopes of bringing European football to Dingwall next season could be over by the time this match kicks off, as Adams conceded.
"It is not in our hands," he said."All we can do is watch Saturday's results and take it from there. The European challenge might be over by the time we play.
"Dundee United have to win at Caley Thistle and St Johnstone have to lose against Celtic. It will become clearer before we go into Sunday's game."
