According to her club boss, the England defender could miss the Women's European Championship due to an injury.
England won the Arnold Clark Cup without Houghton, who was injured last month.
After a four-month lay-off, the 33-year-old returned to action for Manchester City in January.
The return for the Euros is going to be tight according to City boss Taylor.
When Manchester City won the Women's Continental League Cup last week, they were pictured with a cast on her leg.
Taylor said it will be difficult for him to make the World Cup team.
The City manager said that her goal was to get to the Euros.
She is continuing with her rehabilitation after surgery.
She is going to give it everything and we will support her in that as best we can.
There is another two or three weeks before we can estimate her progress and give more news.
While on national team duty in September, she suffered an injury that would affect her for the rest of the year.
She hasn't played for Sarina since she took over as Lionesses boss last summer.
