Dhindsa and Gujral will file their nomination papers tomorrow in the state assembly, a party statement quoting SAD Secretary and Spokesman Daljit Singh Cheema said.
Both Dhindsa and Gujral are sitting RS members whose term will end next month.
The election to five RS seats from the state is slated for March 21.
Besides Dhindsa and Gujral, the term of Avinash Rai Khanna (BJP), Manohar Gill and Ashwani Kumar (both Congress) is also coming to an end next month.
BJP is likely to field former MP Navjot Singh Sidhu for the elections to the Upper House.
