Royal Challengers Bangalore pace spearhead Zaheer Khan, who on Wednesday trained hard at the National Cricket Academy under the watchful eyes of coach Ray Jennings having recovered from an injury, skipped the team's net session on Thursday.
Zaheer arrived at the NCA on Thursday but did not take to the field.
The left-arm fast bowler was seen consulting NCA head physio Ashish Kaushik, before leaving the venue for a routine fitness check-up.
"It is just a routine check-up and we are hoping for the good," a Royal Challengers Bangalore official said.
Zaheer had sustained a calf injury during Mumbai's Ranji Trophy game against Gujarat last December. He was dropped from the Indian Test squad against England.
Meanwhile, Murali Karthik bowled at the nets much to delight of the RCB batsmen, who desperately wanted to face an exemplary spinner like him.
Karthik has a good record in the T20s with an economy rate of close to seven and 93 wickets in 127 matches.
The slow left arm orthodox bowler, who was roped in by RCB after Pune Warriors released him from their squad, looked confident. Earlier he was with Kolkata Knight Riders.
Pankaj Singh, Vijay Zol, Sheldon Jackson, Abhinav Mukund, Harshal Patel, Arun Karthik, Syed Mohammad and KP Appanna also trained hard at the camp ahead of their series opener against Mumbai Indians to be held on April 4 in Bangalore.
Australia all-rounder Daniel Christian is expected to arrive in the city on Thursday night, while Sri Lankan spin legend Muttiah Muralitharan is scheduled to reach on Friday.
