Kyrie Irving says it’s ‘frustrating’ to be sidelined at this point in the regular season.

Dallas Mavericks superstars Luka Doncic and Kyrie Irving missed their third straight game Wednesday as the team began a three-game road trip against the San Antonio Spurs. Doncic remains out with a left thigh strain that has sidelined him since March 11. Irving is dealing with right foot soreness.

“I took a wrong step in New Orleans [on Mar. 8] and just felt like my knuckles cracked and just wanted to take precautionary [measures] at this point in the season,” Irving said Wednesday morning after shootaround in San Antonio.

“I make my whole entire living with my feet. So, I’d rather take care of it now than be dealing with it when I’m 40 years old.”

Without its superstar backcourt, the Mavericks lost a two-game set against the Memphis Grizzlies.  Dallas entered Wednesday’s matchup sitting in a three-way tie with the eighth-place Thunder and 10th-place Lakers with less than one month until the postseason.

“It’s frustrating for any of us that are on the sideline, especially this time in the season,” Irving said. “This is where you want to be playing your best basketball.

“With us being such a newly-developed team at this point in the season, things have to happen a lot sooner. We’d love to be out there, including myself. [But we’ve] just got to get our health right first, and then try to make a push towards the end of the season.”

Doncic and Irving (since being traded to Dallas last month) combine to average 60.5 points, 13.7 rebounds, 14.6 assists and 2.7 steals while each shoots 50% or better from the field.
