Euro 2012 qual. - Fletcher returns to boost Scotland
Fletcher has not featured for his country in 2011 after being struck down by a virus in the spring and Scotland manager Craig Levein admitted earlier this month he would need to make "exceptional" progress to make the Hampden double-header.
But the Manchester United midfielder was named in the squad for the games against the Czechs on September 3 and Lithuania three days later.
Fletcher was sidelined by the virus, which caused sudden weight loss, for two months between early March and early May.
Despite playing 90 minutes against Blackpool in United's final Premier League match of last season and making the substitutes' bench for the Champions League final, Fletcher suffered a relapse in the summer and missed his club's pre-season tour of the USA.
But the 27-year-old played two full reserve games against Arsenal and Swansea this week and Sir Alex Ferguson this morning confirmed the midfielder would be in his squad to face Arsenal on Sunday.
Celtic winger Kris Commons, who was ruled out of the friendly win over Denmark earlier this month with a foot injury but has since returned to club action, is not included in the 25-man squad.
